The proliferative activity of myelokaryocytes and the cellular composition of the bone marrow

: Flow cytometry was used to study myelokaryocyte distribution according to the stage of the cellular cycle in 167 bone marrow specimens 94 of which were taken by puncture from hemoblastosis and anemia patients. The results obtained were compared with myelogram data. It has been established that the method provides stable and reliable values, irrespective of cellular composition of the puncture specimens. Basing on the recurrent algorithm of J. H. Fridman's classification, a computer program has been derived that permitted differential diagnosis to be made based on the data of cytometry and myelogram.
